Abramovich biggest mistake was letting mou leave. chelsea would have been as strong as bayern by now if not more. he built a team from scratch with a mixture of young talent and experience. he had the foundation in place for long term success. but Abramovich wanted immediate success and as we all know that doesnt happen. he wanted world beaters in a matter of months. Madrid, United, barca etc didnt become as big as they are over night.

Im unsure about this, if Mourinho does come back to Chelsea Abramovich needs to give him the reins at the club to steer them back on course. But I truly don't see that happening and may end back at square one seeing as they both may let there egos get in the way of business.
